Dormant supply from when bitcoin traded near $10 is resurfacing as Coinkite's $114M Coldcard exploit sends long-term holders back to audit old storage setups, with the receiving address already wired…
Coldcard losses alone climbed past $100M as investigators widened the scope, proving a vendor-level flaw can drain thousands of cold wallets at once.
The market backdrop remains cautious, with BTC dominance at 56.8%, an Altcoin Index score of 45/100 and Fear & Greed at 25, or Extreme Fear.
The $114M drained from best-practice self-custody users is the strongest argument yet that holding your own keys still means trusting the silicon.
The 77,000 BTC moving isn't selling pressure; it's users fleeing a hardware-wallet bug. Every bearish on-chain reading this week is suspect, since the largest flow since FTX wasn't economic, it was…
The disconnect is the story: spot ETFs absorbed $170M while retail sat in Extreme Fear and Strategy sold 1,638 BTC into the bid without breaking $63K.
Galaxy Research has traced 1,596 BTC stolen across three confirmed attack waves, with a suspected fourth wave that would push total losses to roughly 2,000 BTC.
Four Coldcard wallet sweeps have drained hundreds of BTC, yet BTC still trades above $63,000. The bid is treating it as a per-holder operational leak rather than a protocol-level event.
The 55% surge in on-chain activity is the cleanest real-time signal that the Coldcard breach is forcing users to move funds, not just talk about it.
The figure is roughly twice the early read on the incident and lands Coldcard inside a growing supply-chain risk tier no Bitcoin custodian can ignore.
A March 2021 firmware flaw keeps paying out three years later, and the attacker is now grinding smaller balances through a third wave that hides its collector addresses.
Roughly $38M has been swept from single-sig seeds generated between 2021 and 2023, and the exploit is unpatchable by design: any firmware fix would tip off attackers to wallets still holding funds.
The seed-randomness flaw had lurked in firmware since March 2021 and went unnoticed for years, exposing the practical ceiling of single-device self-custody for serious BTC holders.
Galaxy mapped the July 30 sweep to 1,196 wallets and 1,082 BTC drained in 41 minutes via a seed-generation bug that collapsed the keyspace to a few billion options.
BTC is on track to close July up about 7.5% despite rate-hike fears, climbing yields and an AI-led equity unwind, with analysts pointing to a late-June leverage flush as the reason there was no…
Nearly 1,200 addresses and 1,000 BTC later, the incident has crossed from isolated phishing to a coordinated drain, putting self-custody users on notice about supply-chain risk in hardware wallets.
A three-year gap between Coldcard's final Mk3 firmware and the advisory turns dormant cold-storage wallets into a maintenance liability, with one signature and no passphrase as the worst-case custody…
The $38M theft from a single compromised wallet makes this the largest hardware-wallet supply-chain attack on record, with Coldcard pointing users straight at a firmware load-bearing weakness.
Crypto sat out the sharpest equity rebound of the year, with BTC holding $64,300 even as a $38M Coldcard wallet exploit swept 594 bitcoin off-chain without moving the tape.
The single-signature wallets swept had been dormant for years, but the underlying firmware bug has been live since March 2021, with paper wallet keys and seed-splitting masks exposed too.
